503 error just means it was down for maintenance (totally possible if it's a new site and they overlooked a minor detail or two) or it got too much traffic to handle at that moment. The way the error is worded, sounds more like a problem on Joseph's end.

It's just worded badly. It basically means that the site's Web server is down or overloaded.

Exactly. Error 503 is a standard HTTP error code, so the possible reasons are fairly limited.
